[Upgrade Jobs] DLRN not building package for deployment release

[yatin]

Tested via https://review.rdoproject.org/r/c/testproject/+/38542.

So with an upgrade job for ex. Victoria to Wallaby depends-on are added for both stable/victoria and stable/wallaby, For victoria deployment DLRN not building package for stable/victoria depends-on.
For Wallaby Depends-On, package is built and installed fine.

This is a tracker bug to investigate/fix this scenario. Attempts to fix https://review.opendev.org/c/openstack/tripleo-quickstart-extras/+/826284. For some cases it would be useful to get this fixed.

02:55:58 PM - jfrancoa: yes, agree...if we plan to support soon an FFU job upstream we need that functionality working
02:56:13 PM - jfrancoa: as there will be changes required in train which you can verify only via depends-on

[Bogdan Dobrelya (bogdando)]

Note that the job setting 'override-checkout: stable/victoria' would build DLRN for stable/victoria patches, but we need to make it building both src and dst targets for upgrade

Created an RFE for DLRN to support force checkout https://github.com/softwarefactory-project/DLRN/issues/39

    Allow dlrn builds from both deploy release and upgrade release

    DLRN with --local and --dev options uses whatever already checked
    out source and distgit[1]. So in order to get packages build for
    multiple releases like in upgrade jobs we need to prepare both
    source(git clean and git checkout) and distgit(remove it so
    DLRN fetches it based on config).

    Also use release var to compute what change to build when it's
    defined, when not defined use zuul override-checkout or branch.
    Additionally add non-cached fact artg_change_list_prep to compute
    the changes list as using artg_change_list causes inclusion of
    changes from previous run.
